This study was conducted to evaluate the meat characteristic of crossbred local chicken fed diet containing both dahlia tuber powder as inulin source and probiotic Lactobacillus sp. The experimental animals were 168 crossbred local chickens which were randomly divided into 6 groups of treatment (4 replications each) when they were 21-d old. A completely randomized design with 2 x 3 factorial pattern consisted of 2 levels of prebiotic [(0.8% (D1) and 1.2% (D2)] and 3 levels of probiotic [without probiotic (L0), 1.2 mL (L1), and 2.4 mL (L2)] was arranged in the present study. One mL probiotic (Lactobacillus sp.) was equal to 108 cfu. Results showed that the supplementation of prebiotic and probiotic significantly (P<0.05) affected breast meat color in terms of L* (lightness) and b* (yellowness). The meat fat mass and cholesterol was significantly (P<0.05) decreased by the combination of prebiotic and probiotic. The hardness of meat was not affected significantly by all treatments. The conclusion is that breast meat color could be improved, and both meat fat mass and cholesterol content could be decreased by feeding a combination of 1.2% dahlia tuber powder as inulin source and 1.2 mL probiotic Lactobacillus sp.

The research was aimed to evaluate the inclusion effect of dahlia tubers inulin (DTI) combined with Lactobacillus sp. in dietary protein step down on villi development and growth of KUB chicken. The experiment was arranged in a completely randomized design using 160 birds of one-day-old KUB chicks (body weight was 26.32±1.19 g) divided into 5 treatments with 4 replications. The treatment applied were: (1) P180S: ration with 18% protein with the addition of 1.2% DTI and 1.2 mL (108 cfu/mL) Lactobacillus sp. provided since one-day-old, (2) P15: ration with 15% protein without DTI and Lactobacillus addition and was given from 8-day old, (3) P18: ration with 18% protein without DTI and Lactobacillus addition and was given from 8-day old, (4) P15S: ration with 15% protein with the addition of 1.2% DTI and 1.2 mL Lactobacillus sp. offered from 8-day old, and (5) P18S: ration with 18% protein with the addition of 1.2% DTI and 1.2 mL Lactobacillus sp. offered from 8-day old. The experimental birds allocated in the treatments 2 to 5 were fed ration with 21% protein from hatching until 7-day old. Variables observed were the jejunal pH, total Coliform and lactic acid bacteria (LAB), villi height, protein digestibility, final body weight, and carcass percentage. Data were subjected to analysis of variance (ANOVA), and followed by orthogonal contrast test. Orthogonal contrast test showed that feeding 18% dietary protein fortified with a combination of 1.2% inulin dahlia tuber and 1.2 mL Lactobacillus sp. given since one-day-old significantly (P<0.05) affected the height of jejunal villi, protein digestibility, carcass percentage, final body weight, jejunal pH, and Coliform number. In conclusion, feeding 18% dietary protein fortified with a combination of 1.2% of inulin dahlia tuber and 1.2 mL of Lactobacillus sp. since one-day-old increases the height of the jejunum villi and growth of KUB chicken.

The purpose of the study was to examine the supplementation effects of glucomannan extracted from a porang tuber (GEPT) on body resistance and growth performance of broiler chickens. A total number of 160 one-day-old broiler chickens with the average body weight of 42.39±0.58 g was kept for 35 days. The study was arranged in a completely randomized design with 5 treatments and 4 replications (8 birds each). The dietary treatments were T0= basal ration, T1= basal ration with the addition of 0.05% GEPT, T2= basal ration with the addition of 0.1% GEPT, T3= basal ration with the addition of 0.15% GEPT, and T4= basal ration with the addition of 0.2% GEPT. Parameters measured were the population of lactic acid bacteria (LAB), Coliform count, relative weight of lymphoid organs (bursa fabricius and spleen), heterophils-lymphocytes (H/L) ratio, body weight gain, feed consumption, feed conversion ratio, and mortality. Data were subjected to analysis of variance (ANOVA) and continued with Duncan Multiple Range Test (DMRT) at 5% probability. The results showed that supplementation of the diets with GEPT significantly increased (P<0.05) LAB population, decreased (P<0.05) Coliform count in the jejunum and ileum, and H/L ratio, but did not affect the relative weight of lymphoid organs, and growth performance. In conclusion, diet added with 0.1% GEPT improved the balance of intestinal microflora and increased body resistance, without any negative effects on the lymphoid organs and growth performance of broiler chickens.

The effect of dahlia tuber extract or Lactobacillus acidophilus inclusion on intestinal physiology, antioxidant enzymes, and growth performance of broiler chicken given a microparticle protein-composed diet was evaluated in the present study. Three dietary treatments were applied, Control: 21% intact protein diet without additive, MP-DTE: 21% microparticle protein diet + 1.2% dahlia tuber extract as inulin source, and MP-La: 21% microparticle protein diet + 1.2 mL L. acidophilus (1 mL L. acidophilus/La equal to 108 cfu). Microparticle proteins were obtained from common protein source ingredients for poultry, fish meal, and soybean meal. A completely randomized design was assigned with 3 treatments and replicated 8 times, 10 broilers in each replication. Experimental animals were 240 broilers for treatment and 10 birds for endogenous correction. Digestibility of protein and essential amino acids, villi height, intestinal bacterial counts (LAB and Eschericia coli), short chain fatty acids/SCFA (acetate, propionate, and butyrate), antioxidant enzymes (GSH-Px and SOD), and growth performances (meat protein/MPM and fat mass/MFM, feed consumption, body weight gain/BWG, and feed conversion ratio/FCR) were variables measured. Data were statistically processed based on analysis of variance and continued to the Duncan test (p<0.05). Supplementation of dahlia inulin extract or L. acidophilus to the micropaticle protein diet significantly (p<0.05) increased N retention, villi height, LAB population, SCFA, antioxidant enzymes, and improved MPM and BWG, but decreased E. coli count, MFM, and FCR. However, feed consumption was not affected by any treatment. It can be concluded that L. acidophilus supplementation to the microparticle protein diet (MP-La) improves antioxidant enzymes, and growth performance with high meat protein and low fat mass.
